Morphological features of mucoperichondria in patients with post-traumatic deformity of nasal septum

Over the past decades, surgical techniques have been improved, aimed at restoring the position of the nasal septum in case of its deformities. The attitude to the technique of the operation itself has changed, which consists in a sparing approach to the osteochondral skeleton of the nasal septum (NS). It should be noted that to date, the histological features of the mucous membrane (MM) of NS have not been studied with pronounced curvatures of PN, in this regard, the purpose of our work was to conduct a histological study of the MM of NS and to identify the morphological features of the structure of mucoperichondria in the area of septal deformity. Research methods. Our study included 24 patients with nasal septum deviation (NSD) and concomitant vasomotor or hypertrophic rhinitis. All patients noted impaired nasal breathing. 12 men and women were examined, the average age of the patients was 36 ± 10 years. Patients with grade III of NSD according to the classification of Protasevich were examined and operated on. We analyzed the material taken from 5 loci of the MM of NS. A total of 120 histological sections were examined. When describing histological findings from loci A-E, we were guided by the frequency of occurrence of criteria indicating the severity of irreversible post-traumatic changes in MM of NS. After analyzing the material obtained and carrying out a comparative analysis of the frequency of occurrence of histological findings in each locus, we concluded that the proximity of the locus to the most deformed part of the nasal septum is characterized by the maximum severity of dystrophic and sclerotic changes in the MM of NS, similar to the histological picture of a hypertrophic scar.
